A kind of sandy saline-alkali land soil remediation device and its remediation method

Abstract

The invention discloses a soil restoration device for sandy saline-alkali land, which comprises a water storage sponge, a bottom plate, a water-absorbing sponge, a shell and a top plate. Multiple mounting holes are evenly spaced. In the present invention, a water-absorbing sponge is provided inside the shell between the upper platen and the lower platen, and a water-storage sponge is provided inside the shell above the partition, and plants are planted on the soil above the shell, which not only facilitates the utilization of water-absorbing The sponge absorbs the groundwater in the deep layer of the soil and then discharges it, preventing the water dissolved in the ground from rising to the soil surface through capillary action to evaporate to form a saline-alkali land, which is convenient for collecting the rainwater that penetrates into the shell, and cleans the inside of the shell and the drainage pipe. Cleaning, prolonging the service life of the device, the water storage sponge placed above the partition increases the humidity of the upper soil, which is convenient for the growth of plants, and the upper soil is treated and repaired, thereby improving the effect and efficiency of saline-alkali land treatment.

Description

technical field [0001] The invention relates to the technical field of soil restoration, in particular to a sandy saline-alkali soil restoration device and a restoration method thereof. Background technique [0002] Saline-alkali land is a type of salt accumulation, which means that the salt contained in the soil affects the normal growth of crops. According to the incomplete statistics of UNESCO and FAO, the area of ​​saline-alkali land in the world is 954.38 million hectares, of which my country is the largest 99.13 million hectares, the formation of alkaline soil and alkalized soil in my country is mostly related to the accumulation of carbonate in the soil, so the degree of alkalization is generally high, and plants in severe saline-alkali soil areas can hardly survive. [0003] All kinds of saline-alkali soils are formed under certain natural conditions. The essence of their formation is mainly the redistribution of various soluble salts in the horizontal and vertical di...

Problems solved by technology

[0005] The purpose of the present invention is to provide a sandy saline-alkali soil repair device and its repair method, to solve the problem that the existing saline-alkali land proposed in the above background technology has no efficient treatment method, and can only be carried out by traditional soil overturning and repeated planting preparation. Saline-alkali is suppressed, but the work efficiency is low and the treatment effect is relatively poor. The manpower and material resources are invested heavily, and the treatment effect is not obvious.
